Thanks!  Indeed no crash.

But the first output is:
    QCoreApplication::arguments: Please instantiate the QApplication object 
first

-- which one can easily fix by moving the declaration to top of main()


The next output is:
    Attribute Qt::AA_UseOpenGLES must be set before QCoreApplication is 
created.

-- this is harder because it comes from set_opengl_backend(), which needs the 
options parsed; however it seems that you need QApplication before parsing the 
options.  (?)
-- but maybe one doesn't need to force the opengl backend (?) I think Qt 
chooses one dynamically?
-- I suppressed it by just removing the call to set_opengl_backend()


After all that, nothing plays because -- as you said -- no video renderers are 
available.
